  FIG. 4 is a perspective view of the interlocking mechanism 140. In FIG. 4, the upper right side of the page is the indoor side, and the lower left side of the page is the outdoor side. The interlocking mechanism 140 is provided inside the scissors 132, 133, and 134 above the shoji 130. The interlocking mechanism 140 includes a base body 141, a pair of pulleys 142 and 143 attached to both ends of the base body 141 so as to be rotatable about the center thereof, and an annular shape attached to the pair of pulleys 142 and 143. A wire 146 is provided. The wire 146 is indicated by a broken line for easy viewing (hereinafter, the wire 146 is similarly indicated by a broken line). Further, in the wire 146, a first interlocking member 144 is attached to a part of the indoor portion 146a, and a second interlocking member 145 is attached to a part of the outdoor portion 146b. The length of the interlocking mechanism 140 (pulley spacing direction) is sized so as to be concealable inside the upper part of the shoji 130. The first interlocking member 144 and the second interlocking member 145 include attachment members 144b and 145b, respectively, and the attachment members 144b and 145b are fixedly attached to the wire members 146a and 146b. Magnets 144a and 145a are arranged so that one surface is in contact with attachment members 144b and 145b and the other surface substantially parallel to the moving direction of the shoji is exposed. Accordingly, the magnet 144a of the first interlocking member 144 is disposed with one surface exposed on the indoor side, and the magnet 145a of the second interlocking member 145 is disposed with one surface exposed on the outdoor side. Moreover, the magnets 144a and 145a protrude outside the shoji 130 via slits 138 (see FIG. 3) and 139 (not shown) provided in the collar 134.

  According to the interlocking mechanism 140, when a force in the opening / closing direction of the shoji is applied to the wire 146, the pulley rotates, and the wire 146 and the first and second interlocking members 144 and 145 attached to the wire also move in the horizontal direction. Can do. The first and second interlocking members 144 and 145 move in directions opposite to each other. At this time, the first and second interlocking members 144 and 145 move along slits 138 (see FIG. 3) and 139 (not shown).

  Next, the positional relationship of each component of the opening device 100, the interlocking mechanism, and the like will be described. FIG. 5 is a top view of the opening device 100 in a closed state. For the sake of explanation, the inside is shown as appropriate. In FIG. 5, the upper side of the paper is the indoor side, and the lower side of the paper is the outdoor side. The shoji 110 and the shoji 130, and the shoji 130 and the shoji 150 are arranged in a state where the end portions in the width direction overlap each other in the closed posture of the opening device 100. The interlocked member 116 of the shoji 110 and the first interlocking member 144 of the shoji 130 are arranged facing each other at the overlapped portion. At this time, the interlocked member 116 and the first interlocking member 144 are disposed so as to protrude from the shoji 110 and shoji 130, but do not exist on the trajectory of movement and do not collide on the side surfaces. Since the interlocked member 116 and the first interlocking member 144 are attached so as to expose one surface that is substantially parallel to the moving direction of the magnetic shoji, the interlocked member 116 and the first interlocking member 144 are attracted in the indoor and outdoor directions. It will be in the connected state. On the other hand, the shoji 130 and shoji 150 are also arranged so that the interlocked member 156 of the shoji 150 and the second interlocking member 145 of the shoji 130 face each other at the overlapping portions of the end portions. Also in this case, the interlocked member 156 and the second interlocking member 145 are arranged so as to protrude from the shoji 150 and shoji 130, but do not exist on the trajectory of movement and do not collide on the side surfaces. Thus, for the same reason, the interlocked member 156 and the second interlocking member shoji 145 are connected by a magnetic force attracting in the indoor and outdoor directions.

  FIG. 6 is a top view of the opening device 100 illustrating a state where the shoji 150 is operated from the state of FIG. 5 to open the opening device 100. FIG. 6 (a) shows a closed state, FIG. 6 (b) shows a state where it is partially opened, and FIG. 6 (c) shows a state where the opening is completed. When the shoji 150 is moved in the direction indicated by the straight arrow from the state of FIG. 6A, the interlocked member 156 attached to the shoji 150 also moves following the shoji 150. At this time, since the interlocked member 156 and the second interlocking member 145 are connected as described above, the second interlocking member 145 also moves following the interlocked member 156. With this movement, the outdoor portion of the wire 146 moves to the left side of the drawing, and thereby the indoor portion of the wire 146 moves to the right of the drawing. Further, the first interlocking member 144 attached to the indoor side of the wire 146 moves following the movement of the wire 146. However, since the first interlocking member 144 is connected to the interlocked member 116 attached to the shoji 110, its position cannot be changed, and instead, the shoji 130 moves to the left side of the page. The shoji 110, 130, and 150 move in conjunction with each other as described above. In the opening device 100, the shoji 130 can also move in conjunction with opening and closing the shoji 150. At this time, the ratio of the moving amount of the shoji 150 and the moving amount of the shoji 130 is 2: 1 due to the nature of the interlocking mechanism 140. If the shoji 130 and the shoji 150 are set to have substantially the same width, the shoji 150 When reaching the opening completion position, the shoji 130 also reaches the opening completion position almost simultaneously. Conversely, in order to close the opening device 100 from the open state of FIG. 6C, it is only necessary to move back to the above movement.

  Next, after removing the shoji 130 and 150, the state of each member when reattaching is shown. FIG. 7 is a top view showing one scene in which the shoji 130 is attached. In the opening device 100, the attaching and detaching operations are based on the so-called “Kendon type”. As described above, the shojis 130 and 150 of the opening device 100 can be attached without being aware of the connected portions. As shown in FIG. 7A, the shoji 130 can be attached to an arbitrary position on the movement path of the shoji 130. Since the interlocked member 116 and the first interlocking member 144 are not on the movement trajectory, there is no need to be aware of the collision between the interlocked member 116 and the first interlocking member 144. Therefore, the shoji 130 may be attached at a position separated from the shoji 110 or at a position overlapping the shoji 110. In general, since it is more convenient for the operator to attach to the position separated from the shoji 110, FIG. 7A shows the case of being attached to the position separated from the shoji 110. At this time, the interlocked member 116 of the shoji 110 and the first interlocking member 144 of the shoji 130 are not connected because they are in a separated position. Therefore, the interlocking mechanism 140 does not move. Next, the shoji 130 is moved so that the arrangement shown in FIG. As a result, the interlocked member 116 and the first interlocking member 144 are connected for the first time by magnetic force, and the shoji 110 and shoji 130 are interlocked via the interlocking mechanism 140.

  FIG. 8 is a top view of the opening device 100 when the shoji 150 is further attached from the state of FIG. The shoji 150 is attached to an arbitrary position on the track from the state of FIG. At this time, since the user does not need to be aware of the position where the shoji 150 is attached, it is not necessary to perform an operation such as shifting the position of the shoji 130 already attached for position adjustment, and the shoji 150 can be attached. This greatly improves the convenience for the user. After the shoji 150 is attached, the interlocked member 156 and the second interlocking member 145 are connected by a magnetic force by moving the shoji 150 to the right side of the page. Further, as shown in FIG. 9A, if the shoji 130 already attached is moved to the leftmost side of the page and then the shoji 150 is attached, there is no overlapping shoji when the shoji 150 is attached. The operability is good. After the shoji 150 is attached as shown in FIG. 9A, the interlocked member 156 and the second interlocking member 145 can be coupled by magnetic force by moving the shoji 150 to the left side of the page.

  As described above, the opening device 100 according to the present invention has the convenience that the other shoji can be moved in conjunction with the operation of one shoji, and the shoji is attached without being aware of the attachment position. Therefore, the convenience of the user can be improved. This is also very useful because the sliding doors are inherently more removable than other opening devices.

  FIG. 10 shows that when the shoji 150 is vigorously moved in the closing direction for any reason and the operated hand is released from the shoji 150 before the shoji reaches the closed position, the shoji 150 moves on the trajectory. It is a top view when there is an object 800. In this case, if there is an obstacle 800 as shown in FIG. 10A, the force applied to the obstacle 150 is applied to the obstacle 800 at the time of a collision, and there is a possibility that the obstacle 800 is seriously damaged. In particular, when the obstacle 800 is a human hand or the like, it may lead to a serious injury, and it is desired to avoid it. In addition, the obstacle 800 is damaged, and the impact is transmitted to the shoji as a reaction, which may cause damage to the shoji connecting portion. In such a case, in the case of the opening device 100, if the force to be coupled by the magnetic force between the interlocked members 116 and 156 and the first and second interlocking members 144 and 145 is appropriate, FIG. As shown in FIG. 5, for example, the connection between the interlocked member 156 and the second interlocking member 145 can be released against an abnormal force. Thereby, it is possible to prevent all of the force applied to the shoji 150 from being transmitted to the obstacle 800 and the shoji 110, 130, 150. Thus, the opening part apparatus 100 has the effect excellent also in safety.
